Investigation of pore system properties of carbonate reservoirs has an important role in evaluating the reservoir quality and delineating high production intervals. The current study proposes a three-step approach for pore throat size characterization of these reservoirs, by integrating core data, well logs and 3D seismic volume. In this respect, first the pore throats size was calculated using...

S U M M A R Y We present a significant addition to the data set of traveltimes of seismic PKP waves that sample the Earth’s lowermost mantle and core along the Earth’s rotation axis. Recorded at permanent Global Seismic Network (GSN) and temporary SSCUA deployment broadband seismographic stations in Antarctica, the new data improve the previously poor and biased coverage that underlies the seis...

Introduction: The Silverpit impact structure was discovered during 2001 on three-dimensional (3D) seismic data obtained during routine hydrocarbon exploration in the southern North Sea [1]. It is now known that five commercially-acquired 3D seismic datasets partially cover the structure and approximately 80% of Silverpit is imaged by high-resolution 3D data (Figure 1). Two boreholes had been dr...

In this research seismicity parameters, repeat times and occurrence probability of large earthquakes are estimated for 35 seismic lineaments in Persian plateau and the surrounding area. 628 earthquakes of historical time and present century with MW>5.5 were used for further data analysis. A probabilistic model is used for forecasting future large earthquake occurrences in each chosen lineament....

Abstract High-quality seismic data contributes to improving the prediction accuracy of complex reservoirs. Currently, there are numerous methods for enhancing pre-stack gather resolution and signal-to-noise ratio (SNR). Meanwhile, avoid incorrect interpretation, we must evaluate whether processed maintains its original characteristics reliability. This paper establishes an integrated workflow o...

A combination of two independent geodetic solutions using data from close to 300 continuous GPS stations covering the central and eastern U.S. shows that surface deformation in the North American plate interior is best fit by a model that includes rigid rotation of North America with respect to ITRF2000 and a component of strain qualitatively consistent with that expected from Glacial Isostatic...
